BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a training machine, and more particularly to a waist-training machine that can be operated with different angles and can be folded for being conveniently stored and carried.

2. Description of Related Art

A conventional waist-training machine has a base, a track and a sliding kneeler. The track is curved and is mounted on the base and has a handle. The sliding kneeler is slidably mounted on the track. When using the conventional waist-training machine, the legs of a user are positioned on the sliding kneeler and the hands of the user grip the handle. Then, the user can twist his waist and swing legs to enable the sliding kneeler move along the track upwardly relative to the base and this can train the user's waist.

Although the conventional waist-training machine can provide a waist-training effect, the structure of the conventional waist-training machine is fixed and the angle of the track cannot be adjusted. Then, the user cannot train his waist by changing the angle of the track. In addition, the fixed structure of the conventional waist-training machine cannot be folded and this is inconvenient in storage and transportation.

The invention provides a waist-training machine that mitigates or obviates the aforementioned problems.

The connecting end of the upper telescopic pipe 32 extends out of the top end of the lower telescopic pipe 31 and is pivotally connected to the front pivot mount 26 of the track frame 20. The inserting holes 321 are formed through the front side of the upper telescopic pipe 32 at intervals and selectively align with the button hole 312 of the lower telescopic pipe 31, and each inserting hole 321 has a diameter. The through hole 322 is formed through the rear side of the upper telescopic pipe 32, aligns with one of the inserting holes 321 and has a diameter larger than the diameters of the inserting holes 321. The rotating button 33 is screwed in the button hole 312 of the lower telescopic pipe 31 and has a inner end mounted in one of the inserting holes 321 of the upper telescopic pipe 32 to hold the upper telescopic pipe 32 with the lower telescopic pipe 31.

The sliding kneeler 40 is slidably mounted on the track frame 20 and has a sliding mount 41, two wheel axles 42, a pin mount 43, an inserting pin 44, a positioning bolt 45 and a kneeler 46.

The sliding mount 41 may be a rectangular mount, is slidably mounted between the track bars 24 of the track frame 20 and has a bottom, a top, two opposite sidewalls and two axle holes 411. The axle holes 411 are formed through the opposite sidewalls of the sliding mount 41 at an interval.

The wheel axles 42 are respectively and rotatably mounted in the axle holes 411 of the sliding mount 41, and each wheel axle 42 has two ends and two rollers 421. The ends of the wheel axle 42 respectively extend out of the opposite sidewalls of the sliding mount 41. The rollers 421 are respectively mounted around the ends of the wheel axle 42 and are respectively and rotatably mounted on the track bars 24 of the track frame 20, and each roller 421 has an external surface and an annular groove 422. The annular groove 422 is formed around the external surface of the roller 421 and abuts the corresponding track bar 24.

The pin mount 43 is mounted on the bottom of the sliding mount 41 between the track bars 24 and has a bottom, a rear side, a front side, two sidewalls, a buffering face 431, a pinhole 432 and a positioning hole 433. The bottom of the pin mount 43 extends downwardly out of the track bars 24. The buffering face 431 is formed on the rear side of the pin mount 43 and selectively abuts the buffering block 23 of the track frame 20. The pinhole 432 is formed through the sidewalls of the pin mount 43 below the track bars 24. The positioning hole 433 is formed through the front side of the pin mount 43 and communicates with the pinhole 432.

The inserting pin 44 is mounted in the pinhole 432 of the pin mount 43, abuts against the track bars 24 and has a central segment, two ends and a threaded hole 441. The central segment of the inserting pin 44 is mounted in the pin mount 43 between the sidewalls. The ends of the inserting pin 44 respectively extend out of the sidewalls of the pin mount 43 below the track bars 24. The threaded hole 441 is formed in the central segment of the inserting pin 44 and aligns with the positioning hole 433 of the pin mount 43.

The positioning bolt 45 is mounted through the positioning hole 433 of the pin mount 43 and is screwed in the threaded hole 441 of the inserting pin 44 to enable the inserting pin 44 to abut the track bars 24 to prevent the rollers 421 separating from the track bars 24. The kneeler 46 is securely mounted on the top of the sliding mount 41 and has two supporting rods 461 and a hassock 462. The supporting rods 461 are securely mounted on the top of the sliding mount 41 at an interval over the track bars 24 and each supporting rod 461 has a top face. The hassock 462 is securely mounted on the top faces of the supporting rods 461 and has a top and two mounting recesses 4621. The mounting recesses 4621 are formed in the top of the hassock 462 at an interval to aid positioning of the legs of the user.

With further reference to FIG. 6, when using the waist-training machine in accordance with the present invention, the legs of a user are positioned in the mounting recesses 4621 of the hassock 462 and the hands of the user grip the handle sheath 251 of the handle frame 25. The user can twist his waist and swing legs to enable the sliding kneeler 40 to move relative to the base 10 along the track bars 24 of the track frame 20. During the movement of the sliding kneeler 40, the waist of the user can be compressed and trained. In addition, when the sliding kneeler 40 moves upwardly and returns to the rear ends of the track bars 24, the magnetic-induction switch 271 will sense the movement of the sliding kneeler 40 and send a signal to the counter device 27 to show the sliding times of the sliding kneeler 40. Furthermore, the buffering block 23 and the buffering face 431 are respectively mounted on the track frame 20 and the pin mount 43 and this can prevent the impact between the track frame 20 and the sliding kneeler 40.

With reference to FIGS. 3 and 7, when a use wants to adjust the slant angle of the track frame 20 to change the degree of difficulty, the rotating button 33 is rotated to enable the inner end of the rotating button 33 to separate from the corresponding inserting hole 321 of the upper telescopic pipe 32. Then, the upper telescopic pipe 32 can be moved relative to the lower telescopic pipe 321 to change the inserting depth of the upper telescopic pipe 32 so as to adjust the slant angle of the track frame 20. When the track frame 20 has been adjusted to a desired slant angle, the rotating button 33 is rotated to insert into a corresponding inserting hole 321 of the upper telescopic pipe 32 to hold the upper telescopic pipe 32 with the lower telescopic pipe 31.

With reference to FIGS. 8 to 10, when the waist-training machine in accordance with the present invention is folded, the positioning bolt 45 is separated from of the threaded hole 441 of the inserting pin 44 and the inserting pin 44 is separated from the pin mount 43. Then, the pin mount 43, the sliding mount 41 and the kneeler 46 can be removed from the track bars 24 of the track frame 20. After removing the sliding kneeler 40, the rotating button 33 is rotated to enable the upper telescopic pipe 32 to separate from the lower telescopic pipe 31, the upper telescopic pipe 32 is pivoted relative to the track bars 24 by the front pivot mount 26 and the lower telescopic pipe 31 is pivoted relative to the bottom beam 11 by the front hinge mount 14. Then, the track frame 20 is moved downwardly to abut the base 10 and to enable the through hole 322 of the upper telescopic pipe 32 to align with the button hole 312 of the lower telescopic pipe 31 via a corresponding inserting hole 321.

When the through hole 322 of the upper telescopic pipe 32 aligns with the button hole 312 of the lower telescopic pipe 31, the inner end of the rotating button 33 is mounted through the through hole 322 of the upper telescopic pipe 32 and is screwed into the button hole 312 of the lower telescopic pipe 31 to hold the track frame 20 with the base 10 as shown in FIG. 10. Finally, with reference to FIG. 11, the sliding kneeler 40 can be mounted on the track bars 24 of the track frame 20 to reduce the volume of the waist-training machine and this is convenient in storage and transportation.
